Niglon Protego 11 Way Main Switch SPD Consumer Unit
PCU1412M/SPD – 100A Metal Consumer Unit with Type 2 Surge Protection
The Niglon Protego 11 Way Main Switch SPD Consumer Unit is an Electrical4Less combination designed for professional electricians carrying out domestic consumer unit replacements, property rewires and new electrical installations. Featuring a 100A double-pole main isolator, 14-module steel enclosure and Type 2 surge protection, this package provides 11 usable outgoing ways for individual circuit protection.
Based on the original Niglon PCU1412M, this combination includes a compatible single-module Niglon Type 2 SPD and a meter tails gland. The Niglon Protego 11 Way Main Switch SPD Consumer Unit is supplied without outgoing RCBOs, giving installers the flexibility to select protective devices appropriate for their circuits.
Electrical4Less Exclusive – Why 11 Ways Instead of 12?
The Niglon Protego 11 Way Main Switch SPD Consumer Unit is an Electrical4Less-created combination rather than a separate factory-manufactured Niglon SPD consumer unit.
The standard Niglon Protego PCU1412M is a 14-module metal consumer unit with 12 free ways and a 100A double-pole main switch. Niglon does not supply this particular model as a standard factory-packaged SPD version, so Electrical4Less has combined the original consumer unit with a matching Niglon Type 2 surge protection device.
The included single-module SPD occupies one of the original 12 free ways, leaving 11 usable outgoing ways for RCBOs or other compatible protective devices.
Importantly, the SPD connects directly to the consumer unit busbar without requiring a separate MCB. This saves an additional module space and keeps the remaining 11 ways available for circuit protection.
This explains why the Niglon manufacturer’s PCU1412M datasheet specifies 12 free ways, while the Electrical4Less PCU1412M/SPD combination is advertised as an 11-way SPD consumer unit.

Niglon Protego Range – Designed for Professional Electricians
The Niglon Protego range has been developed to provide electricians with practical installation advantages, combining strengthened steel construction with improved internal access and cable management features.
The PCU1412M enclosure measures 304mm wide, 260mm high and 110mm deep, offering a compact single-row arrangement for installations requiring up to 11 outgoing circuits when the included SPD is installed.
A built-in spirit level helps installers position the enclosure accurately before fixing it to the wall. Raised DIN rails provide additional space behind mounted protective devices, helping with cable routing and conductor management.
The Niglon Protego 11 Way Main Switch SPD Consumer Unit also benefits from the range’s versatile cable entry arrangement. Multiple round knockouts allow incoming and outgoing cables to be routed from different positions, while square rear knockouts accommodate cables entering from behind the enclosure.
Additional Protego design features include a reinforced curved steel cover, improved internal terminal arrangements, large terminal screws and provision for neat cable organisation.
These details are especially useful during consumer unit replacements where existing cable positions and available conductor lengths can affect the installation.
11 Usable Ways for Domestic Electrical Installations
The Niglon Protego 11 Way Main Switch SPD Consumer Unit provides a useful balance between enclosure size and outgoing circuit capacity. With 11 usable ways after the SPD is fitted, it is suitable for smaller and medium-sized domestic electrical installations requiring individual circuit protection.
Typical applications may include:
- Domestic consumer unit replacements and electrical rewires.
- Flats, houses and residential extensions.
- Separate lighting circuits for different areas of a property.
- Ring final and radial socket outlet circuits.
- Dedicated cooking appliance supplies.
- Electric shower circuits where appropriately designed.
- Utility room and fixed appliance circuits.
- Garage and external electrical supplies.
- Suitable small commercial installations.
Using individual RCBOs for outgoing circuits can help improve fault discrimination at circuit level, limiting disruption to other circuits when a residual current or overcurrent fault occurs.
The final number of circuits, protective device ratings and circuit arrangement must be determined by the electrician according to the installation design and relevant BS 7671 requirements.
Type 2 Surge Protection with Direct Busbar Connection
The Niglon Protego 11 Way Main Switch SPD Consumer Unit includes a compatible Niglon Type 2 surge protection device intended to help protect connected electrical equipment against transient overvoltages.
Transient overvoltages may occur due to electrical network switching operations and indirect lightning-related events. These short-duration voltage disturbances can affect electronic equipment connected to the electrical installation.
Modern residential properties contain a growing amount of sensitive electronic equipment, including televisions, computers, smart home controls, heating controls, network equipment and appliances incorporating electronic circuit boards.
The supplied SPD is a single-module device designed for direct busbar connection in the specified Protego consumer unit arrangement. No separate MCB is required for this configuration, allowing the original 12-way board to retain 11 outgoing ways.
The surge protection device must be installed in accordance with its manufacturer’s instructions, including suitable earthing, connection arrangements and protective coordination.
100A Double Pole Main Switch and Right-Hand Incomer
The original Niglon PCU1412M consumer unit incorporates a 100A double-pole main isolator, providing a means of isolating the consumer unit assembly.
The right-hand incomer arrangement allows electricians to plan the incoming supply connections around the designated main switch position.
The main switch features a twin-screw terminal arrangement, with a manufacturer-specified terminal capacity of 35mm². The consumer unit is rated for 230V AC operation at 50Hz.
The 100A rating is the manufacturer’s rating of the main isolator and assembly. The installation must be assessed against the supply characteristics, upstream protection, cable sizing and relevant electrical installation requirements.
Meter Tails Gland Included
The Niglon Protego 11 Way Main Switch SPD Consumer Unit is supplied by Electrical4Less with a meter tails gland, included alongside the original consumer unit and Type 2 SPD.
The gland provides a useful component for routing incoming supply conductors through a suitable enclosure entry, helping electricians achieve a tidy and secure cable entry arrangement when correctly installed.
By including the meter tails gland within the package, Electrical4Less makes it easier to source the main consumer unit components and this installation accessory together.
The gland must be suitable for the selected cable arrangement and enclosure entry.
Compatible Niglon 6kA Bi-Directional RCBOs
The Niglon Protego 11 Way Main Switch SPD Consumer Unit is supplied without outgoing RCBOs, allowing electricians to select individual circuit protection devices appropriate for the installation.
RCBOs combine residual current protection and overcurrent protection within one device. This arrangement allows individual final circuits to be protected separately and can help reduce disruption if a fault develops on one circuit.
Electrical4Less supplies Niglon 6kA bi-directional RCBOs in a selection of current ratings to suit different circuit protection requirements. Protective devices must be selected according to circuit design, prospective fault current and manufacturer compatibility requirements.

Please note that outgoing RCBOs are not included in the PCU1412M/SPD package and must be purchased separately.
